FASD Prevention: Why Both Parents’ Alcohol Use Matters.

Does a father's drinking matter before conception?

Foetal Alcohol Spectrum Disorder (FASD) can occur when a baby is exposed to alcohol during pregnancy. For decades, public health messaging has focused almost entirely on the mother - we now understand the picture is broader.

When it comes to preparing for a healthy pregnancy, it really does take two to tango.

If you’re trying to conceive, you’ve probably been encouraged to prioritise the mother’s health. That matters—but so does the father’s preconception health, including alcohol intake. FASD is most strongly linked to alcohol exposure during pregnancy, and the safest choice in pregnancy is no alcohol.

At the same time, emerging research suggests a father’s alcohol use before conception may influence sperm quality and early embryo development.

This isn’t about blame. It’s about giving couples practical, evidence-informed steps they can take together to reduce risk and feel more in control on the path to pregnancy.

What problems can FASD cause?

Prenatal alcohol exposure can lead to a range of lifelong challenges, including:

- Movement, balance, vision, and hearing difficulties

- Learning challenges (thinking, concentration, memory)

- Emotional regulation and social skills difficulties

- Hyperactivity and impulse-control issues

- Communication and speech difficulties

- Health problems affecting joints, muscles, bones, and organs (including the kidneys and heart)

While these effects can be permanent, early assessment and support can make a meaningful difference to a child’s development and quality of life.

Why both parents matter

Scientists have warned about alcohol in pregnancy for more than 50 years, and research suggests that even low levels of maternal drinking may affect a child’s brain development, cognition, behaviour, and facial development.

More recently, researchers have also highlighted the potential role of paternal health before conception. In simple terms:

A father’s lifestyle choices—including alcohol—may affect sperm and the earliest stages of development through mechanisms such as epigenetic change (changes in how genes are expressed, not changes to the genes themselves). This reinforces a shared responsibility: supporting a healthy pregnancy is something couples can do together.

Takeaway (for couples trying to conceive)

• FASD is preventable: the safest choice in pregnancy is no alcohol.

• Preconception health matters for both partners: alcohol can affect fertility and sperm quality, so it’s worth addressing before trying.

• How long should we stop drinking before trying to conceive?: aim for at least 3 months alcohol-free (or as close as possible) before conception.

• Make it a team approach: agree on a shared plan and support each other—this is about risk reduction, not blame.

• Get support early: if stopping alcohol is difficult, or you’re already pregnant and worried about exposure, speak with your GP/midwife and seek specialist advice promptly.
